When the distance between the vehicle behind and the target vehicle is relatively close, the target vehicle controls the taillight to flash to remind the object behind to give way, so as to reduce the probability of a rear-end collision of the vehicle as much as possible. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 It is a schematic structural diagram of the emergency warning system provided by the embodiment of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further describes in detail the specific embodiments of the present utility model by describing the optimal embodiments with reference to the drawings.

[0021] Figure 1 It is a schematic structural diagram of the emergency warning system provided by the embodiment of the present utility model. For the sake of convenience of description, only the parts related to the embodiment of the present utility model are shown. The system includes:

[0022] Ranging units disposed in front of and behind the target vehicle, the ranging units are communicatively connected to the body control module (BCM) through a CAN line, and the body control module (BCM) is communicatively connected to the headlight and the taillight;

[0023] The ranging unit includes a first ranging unit and a second ranging unit. Among them, the first ranging unit is arranged at the head of the target vehicle and is used to detect the first distance between the obstacle in front of the target vehicle and the target vehicle. The second ranging unit is arranged at the tail of the target vehicle and is used to detect the second distance between the obstacle behind the target vehicle and the target vehicle. The first ranging unit and the second ranging unit respectively send the detected first distance and second distance to the body control module (BCM). When the BCM detects that the first distance is greater than the set safety distance, it controls the high and low beams of the front headlights to switch back and forth. When the BCM detects that the second distance is greater than the set safety distance, it controls the tail lights to flash. The tail lights are brake lights and / or hazard lights.

[0024] When the vehicle in front is at a relatively close distance to the target vehicle, the target vehicle controls the high and low beams of the front headlights to switch back and forth to remind the object in front to give way. When the vehicle behind is at a relatively close distance to the target vehicle, the target vehicle controls the tail lights to flash to remind the object behind to give way, so as to reduce the probability of rear-end collisions as much as possible.

[0025] In the embodiment of the present invention, the system further includes:

[0026] An in-vehicle speaker arranged inside the vehicle, which is communicatively connected to the BCM;

[0027] When the BCM detects that the first distance is greater than the set safety distance, it controls the in-vehicle speaker to remind the driver of the target vehicle to decelerate or change lanes to avoid. When the BCM detects that the second distance is greater than the set safety distance, it controls the in-vehicle speaker to remind the driver of the target vehicle to accelerate or change lanes to avoid.

[0028] In the embodiment of the present invention, the above-mentioned first ranging unit and second ranging unit are millimeter-wave radars or cameras. When the first ranging unit and the second ranging unit collect millimeter-wave radars, the target vehicle cannot determine whether the obstacle is a pedestrian or a vehicle, and can only give prompts through the front headlights and tail lights. When the first ranging unit and the second ranging unit use cameras, based on the cameras, it is possible to determine whether the obstacle in front is a pedestrian or a vehicle. When the obstacle in front is a pedestrian, the above-mentioned prompting unit can use an in-vehicle horn to prompt the pedestrian to give way through the in-vehicle horn.

[0029] In the embodiment of the present invention, the system further includes: a wheel speed sensor, which is communicatively connected to the BCM; the wheel speed sensor outputs the vehicle speed signal of the target vehicle and sends the vehicle speed signal to the BCM. The BCM sets the safety distance based on the vehicle speed. The greater the vehicle speed of the target vehicle, the greater the safety distance value, so as to further reduce the collision risk during the driving process of the vehicle.

[0030] The present utility model also provides a vehicle, which is integrated with the above-mentioned emergency warning system. When the vehicle is relatively close to the obstacle in front and the obstacle behind, by controlling the vehicle's front and rear lights to emit avoidance reminders to the obstacle in front and the obstacle behind, and at the same time, reminding the driver of the target vehicle to avoid through the in-vehicle speaker, the probability of the vehicle having a rear-end collision is reduced as much as possible.

[0031] The present utility model has been described exemplarily. Obviously, the specific implementation of the present utility model is not limited by the above-mentioned manner. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
